BACKGROUND

Artificial Intelligence (AI) can be employed for classification and/or analysis of digital images. For instance, AI can be employed for image recognition. In certain technical applications, AI can be employed for generative modeling such as, for example, a generative adversarial network, to learn data distributions. However, training a generative model and/or generating high quality synthetic images is generally difficult to achieve. For example, accuracy and/or efficiency of pixel-level annotation for synthetic images associated with generative models is generally difficult to achieve. As such, conventional artificial intelligence techniques can be improved.

DETAILED DESCRIPTION

Various aspects of this disclosure are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It should be understood, however, that certain aspects of this disclosure may be practiced without these specific details, or with other methods, components, materials, etc. In other instances, well-known structures and devices are shown in block diagram form to facilitate describing one or more aspects.

Systems and techniques that provide concurrent image and corresponding multi-channel auxiliary data generation for a generative model are presented. For example, a novel generative adversarial network is disclosed herein. The novel generative adversarial network can include, during a training phase, a multi-channel generator that produces multi-channel data and a discriminator that receives in multi-channel data to classify real data or synthetic data. Other information such as segment information, etc. can be encoded in another channel so that learning can be concurrently performed during training. Synthetic multi-channel data can also be generated during an inferencing phase. In an embodiment, the novel generative adversarial network can employ a multi-channel generator associated with a convolutional neural network to generate a synthetic image and two or more segmentations for the synthetic image. The novel generative adversarial network can also employ a discriminator associated with a convolutional neural network to classify real images from multi-channel data related to the synthetic image and the two or more segmentations for the synthetic image. In an aspect, synthetic images for a generative adversarial network can be annotated by concurrently generating corresponding multi-channel auxiliary data. In another aspect, a generative adversarial network can be trained using a loss function that is generated based on multi-channel data generation to tune the generative adversarial network accordingly. In certain embodiments, the novel generative adversarial network can employ concurrent medical image and corresponding multi-channel auxiliary data to improve annotation related to disease detection. For example, the novel generative adversarial network can employ concurrent medical image and corresponding multi-channel auxiliary data without the need of a radiologist to annotate at a pixel level for the synthetic imagery. As such, by employing the novel generative adversarial network as described herein, detection and/or localization of one or more features associated with image data (e.g., detection and/or localization of one or more conditions for a patient associated with medical imaging data) can be improved. Furthermore, accuracy and/or efficiency for classification and/or analysis of image data (e.g., medical imaging data) can be improved. Additionally, effectiveness of a machine learning model for classification and/or analysis of image data (e.g., medical imaging data) can be improved, performance of one or more processors that execute a machine learning model for classification and/or analysis of image data (e.g., medical imaging data) can be improved, and/or efficiency of one or more processors that execute a machine learning model for classification and/or analysis of image data (e.g., medical imaging data) can be improved.

Referring initially to FIG. 1, there is illustrated an example system 100 that provides concurrent image and corresponding multi-channel auxiliary data generation for a generative model, according to one or more embodiments of the subject disclosure.

In one example, the system 100 can be associated with a classification system to facilitate visualization and/or interpretation of medical imaging data. Moreover, the system 100 and/or the components of the system 100 can be employed to use hardware and/or software to solve problems that are highly technical in nature (e.g., related to processing digital data, related to processing imaging data, related to medical modeling, related to medical imaging, related to artificial intelligence, etc.), that are not abstract and that cannot be performed as a set of mental acts by a human.

The system 100 can include a generative modeling component 102 that can include a multi-channel generator component 104, a discriminator component 106, and a training component 108. In an embodiment, the generative modeling component 102 can be employed for a training phase. For example, the generative modeling component 102 can be employed for multi-channel generative adversarial network training. Aspects of the systems, apparatuses or processes explained in this disclosure can constitute machine-executable component(s) embodied within machine(s), e.g., embodied in one or more computer readable mediums (or media) associated with one or more machines. Such component(s), when executed by the one or more machines, e.g., computer(s), computing device(s), virtual machine(s), etc. can cause the machine(s) to perform the operations described. The system 100 (e.g., the generative modeling component 102) can include memory 112 for storing computer executable components and instructions. The system 100 (e.g., the generative modeling component 102) can further include a processor 110 to facilitate operation of the instructions (e.g., computer executable components and instructions) by the system 100 (e.g., the generative modeling component 102).

The generative modeling component 102 (e.g., the discriminator component 106 of the generative modeling component 102) can receive imaging data 114. The imaging data 114 can be two-dimensional imaging data and/or three-dimensional imaging data generated by one or more imaging devices. For instance, the imaging data 114 can be imagery captured via a set of sensors (e.g., a set of sensors associated with an imaging device). In certain embodiments, the imaging data 114 can be a series of imagery captured via a set of sensors (e.g., a set of sensors associated with an imaging device) during an interval of time. The imaging data 114 can be received directly from one or more imaging devices. Alternatively, the imaging data 114 can be stored in one or more databases that receives and/or stores the imaging data 114 associated with the one or more imaging devices. In certain embodiments, the imaging data 114 can be medical imaging data. For example, the imaging data 114 can be two-dimensional medical imaging data and/or three-dimensional medical imaging data generated by one or more medical imaging devices. In example, the imaging data 114 can be electromagnetic radiation imagery captured via a set of sensors (e.g., a set of sensors associated with a medical imaging device). In certain embodiments, the imaging data 114 can be a series of electromagnetic radiation imagery captured via a set of sensors (e.g., a set of sensors associated with a medical imaging device) during an interval of time. In another example, the imaging data 114 can be positron emission tomography (PET) scan imagery. In yet another example, the imaging data 114 can be magnetic resonance imaging (MRI) data. The imaging data 114 can be received directly from one or more medical imaging devices. Alternatively, the imaging data 114 can be stored in one or more databases that receives and/or stores the medical imaging data associated with the one or more medical imaging devices. A medical imaging device can be, for example, an x-ray device, a computed tomography (CT) device, a PET scanner device, an MRI device, another type of medical imaging device, etc.

In an embodiment, the imaging data 114 can be multi-channel imaging data. For example, the imaging data 114 can be a multi-channel data sample of a real image. In an aspect, the imaging data 114 can include a real version of imaging data. Additionally, the imaging data 114 can include one or more segmentations of the real version of the imaging data. For example, in an embodiment, the imaging data 114 can include a first data channel associated with a real image, a second data channel associated with first segmentation data indicative of a segmentation for the real image, and a third data channel associated with second segmentation data indicative of a remaining segmentation for the real image. In certain embodiments, the imaging data 114 can include mask data. For instance, the imaging data 114 can include one or more masks for the one or more segmentations of the real version of the imaging data. In an example, the imaging data 114 can include first mask data indicative of a first mask (e.g., a first ground truth mask) for the first segmentation data and second mask data indicative of a second mask (e.g., a second ground truth mask) for the second segmentation data. A mask included in the imaging data 114 can be a filter to mask one or more regions in the real version of the imaging data. For instance, a mask included in the imaging data 114 can include one or more weights for one or more regions of interest in the real version of the imaging data. In one example, a mask can include a set of pixels that define a location for a segmentation using binary filtering. Additionally or alternatively, the generative modeling component 102 (e.g., the multi-channel generator component 104 of the generative modeling component 102) can receive one or more latent random variables 116. The one or more latent random variables 116 can be sampled, for example, from a data distribution of random variables. For instance, the one or more latent random variables 116 can be a vector of random variables.

The multi-channel generator component 104 can generate synthetic multi-channel data based on the one or more latent random variables 116. The synthetic multi-channel data can be a multi-channel data sample. In an aspect, the synthetic multi-channel data can include a synthetic version of imaging data. Additionally, the synthetic multi-channel data can include one or more segmentations of the synthetic version of the imaging data. The synthetic version of the imaging data and the one or more segmentations can be associated with unique data channels. For example, in an embodiment, the multi-channel generator component 104 can generate a first data channel associated with a synthetic image, a second data channel associated with first segmentation data indicative of a segmentation for the synthetic image, and a third data channel associated with second segmentation data indicative of a remaining segmentation for the synthetic image. In another embodiment, the multi-channel generator component 104 can generate a first data channel associated with a synthetic image, a second data channel associated with first segmentation data indicative of a first segmentation for the synthetic image, a third data channel associated with second segmentation data indicative of a remaining portion of the first segmentation for the synthetic image, a fourth data channel associated with third segmentation data indicative of a second segmentation for the synthetic image, and a fifth data channel associated with fourth segmentation data indicative of a remaining portion of the second segmentation for the synthetic image. However, it is to be appreciated that the synthetic multi-channel data generated by the multi-channel generator component 104 can be associated with a different number of data channels and/or a different number of segmentations. In an embodiment, the synthetic multi-channel data generated by the multi-channel generator component 104 can include mask data. For instance, the multi-channel generator component 104 can generate one or more masks for the one or more segmentations of the synthetic version of the imaging data. In an example, the multi-channel generator component 104 can generate first mask data indicative of a first mask (e.g., a first ground truth mask) for the first segmentation data, the multi-channel generator component 104 can generate second mask data indicative of a second mask (e.g., a second ground truth mask) for the second segmentation data, etc. A mask included in the synthetic multi-channel data can be a filter to mask one or more regions in the synthetic version of the imaging data. For instance, a mask included in the synthetic multi-channel data can include one or more weights for one or more regions of interest in the synthetic version of the imaging data. In one example, a mask can include a set of pixels that define a location for a segmentation using binary filtering.

In another embodiment, the multi-channel generator component 104 can employ a deep neural network such as, for example, a convolutional neural network to generate the synthetic multi-channel data. In certain embodiments, the convolutional neural network can be a spring network of convolutional layers. For instance, the convolutional neural network can perform a plurality of sequential and/or parallel downsampling and/or upsampling of the one or more latent random variables 116 associated with convolutional layers of the convolutional neural network. In an example, the convolutional neural network can perform a first convolutional layer process associated with sequential downsampling of the one or more latent random variables 116 and a second convolutional layer process associated with sequential upsampling of the one or more latent random variables 116. The spring network of convolutional layers can include the first convolutional layer process associated with the sequential downsampling and the second convolutional layer process associated with sequential upsampling. The spring network of convolutional layers associated with the convolutional neural network can alter convolutional layer filters similar to functionality of a spring. For instance, the convolutional neural network can analyze the one or more latent random variables 116 based on a first convolutional layer filter that comprises a first size, a second convolutional layer filter that comprises a second size that is different than the first size, and a third convolutional layer filter that comprises the first size associated with the first convolutional layer filter.

The discriminator component 106 can predict the imaging data 114 with a first predicted class set or a second predicted class set. Additionally or alternatively, the discriminator component 106 can predict the synthetic multi-channel data with the first predicted class set or the second predicted class set. In an embodiment, a class set can include a multi-channel image (e.g., channel level labels), an image label (e.g., image level labels) and/or clinical labels. The first predicted class set can be associated with a first classification (e.g., a first classification label) and the second predicted class set can be associated with a second classification (e.g., a second classification label). For example, an image level label can correspond to a “real” label for an image (e.g., a “real” classification label) or a “fake” label for an image (e.g., a “fake” classification label). In another example, a channel level label can correspond to a “real” label for a multi-channel image (e.g., a “real” classification label) or a “fake” label for a multi-channel image (e.g., a “fake” classification label). In an embodiment, the discriminator component 106 can label the synthetic multi-channel data with a first label (e.g., a “real” label) or a second label (e.g., a “fake” label) based on the first data channel associated with the synthetic image, the second data channel associated with the first segmentation data, and the third data channel associated with the second segmentation data. In another embodiment, the discriminator component 106 can label the synthetic multi-channel data with a first label (e.g., a “real” label) or a second label (e.g., a “fake” label) based on the first data channel associated with the synthetic image, the second data channel associated with the first segmentation data, the third data channel associated with the second segmentation data, the fourth data channel associated with the third segmentation data, and the fifth data channel associated with the fourth segmentation data.

In certain embodiments, the discriminator component 106 can employ a deep neural network such as, for example, a convolutional neural network to label (e.g., classify) the imaging data 114 and/or the synthetic multi-channel data. In certain embodiments, the convolutional neural network can be a spring network of convolutional layers. For instance, the convolutional neural network can perform a plurality of sequential and/or parallel downsampling and/or upsampling of the imaging data 114 and/or the synthetic multi-channel data associated with convolutional layers of the convolutional neural network. In an example, the convolutional neural network can perform a first convolutional layer process associated with sequential downsampling of the imaging data 114 and/or the synthetic multi-channel data and a second convolutional layer process associated with sequential upsampling of the imaging data 114 and/or the synthetic multi-channel data. The spring network of convolutional layers can include the first convolutional layer process associated with the sequential downsampling and the second convolutional layer process associated with sequential upsampling. The spring network of convolutional layers associated with the convolutional neural network can alter convolutional layer filters similar to functionality of a spring. For instance, the convolutional neural network can analyze the imaging data 114 and/or the synthetic multi-channel data based on a first convolutional layer filter that comprises a first size, a second convolutional layer filter that comprises a second size that is different than the first size, and a third convolutional layer filter that comprises the first size associated with the first convolutional layer filter. In certain embodiments, the discriminator component 106 can extract information that is indicative of correlations, inferences and/or expressions from the imaging data 114 and/or the multi-channel imaging data based on the convolutional neural network. In an aspect, the discriminator component 106 can perform learning with respect to the imaging data 114 and/or the multi-channel imaging data explicitly or implicitly using the convolutional neural network. The discriminator component 106 can also employ an automatic classification system and/or an automatic classification process to facilitate analysis of the imaging data 114 and/or the multi-channel imaging data. For example, the discriminator component 106 can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to learn and/or generate inferences with respect to the imaging data 114 and/or the multi-channel imaging data. The discriminator component 106 can employ, for example, a support vector machine (SVM) classifier to learn and/or generate inferences for the imaging data 114 and/or the multi-channel imaging data. Additionally or alternatively, the discriminator component 106 can employ other classification techniques associated with Bayesian networks, decision trees and/or probabilistic classification models. Classifiers employed by the discriminator component 106 can be explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via receiving extrinsic information). For example, with respect to SVM's, SVM's can be configured via a learning or training phase within a classifier constructor and feature selection module. A classifier can be a function that maps an input attribute vector, x=(x1, x2, x3, x4, xn), to a confidence that the input belongs to a class—that is, f(x)=confidence(class).

The training component 108 can employ the first predicted label or the second predicted label for the imaging data 114 to train a generative artificial intelligence model. Additionally or alternatively, the training component 108 can employ the first predicted label or the second predicted label for the synthetic multi-channel data to train the generative artificial intelligence model. The generative artificial intelligence model can be a model for a generative network. For example, the generative artificial intelligence model can be a model for a generative adversarial network. The generative network (e.g., the generative adversarial network) can be employed to generate images and/or corresponding annotations for the images. For example, the generative network (e.g., the generative adversarial network) can be employed to generate medical images and/or corresponding annotations for the medical images. In an embodiment, the training component 108 can generate and/or utilize a loss function to tune the generative artificial intelligence model based on the first predicted label or the second predicted label for the imaging data 114. For example, the training component 108 can generate and/or utilize a loss function to tune a discriminator of a generative adversarial network (e.g., to tune a convolutional neural network for a discriminator of a generative adversarial network) based on the first predicted label or the second predicted label for the imaging data 114. The loss function associated with the imaging data 114 can be, for example, a cross-entropy error function. Furthermore, the generative adversarial network can be modified based on the loss function associated with the imaging data 114 to improve classification output from the generative adversarial network. Additionally or alternatively, the training component 108 can generate and/or utilize a loss function to tune the generative artificial intelligence model based on the first predicted label or the second predicted label for the multi-channel imaging data. For example, the training component 108 can generate and/or utilize a loss function to tune a multi-channel generator of a generative adversarial network (e.g., to tune a convolutional neural network for a multi-channel generator of a generative adversarial network) based on the first predicted label or the second predicted label for the synthetic multi-channel data. The loss function associated with the synthetic multi-channel data can be, for example, a cross-entropy error function. Furthermore, the generative adversarial network can be modified based on the loss function associated with the synthetic multi-channel data to improve generation of an image from a data distribution associated with the generative adversarial network. In certain embodiments, a loss function generated by the training component 108 can include a set of weights to tune one or more parameters of the generative artificial intelligence model. In an embodiment, the generative modeling component 102 can generate a generative model 118. For example, the generative model 118 can be the generative artificial intelligence model trained by the training component 108. In certain embodiments, the generative model 118 can be associated with the loss function related to the imaging data 114 and/or the loss function related to the synthetic multi-channel data.

It is to be appreciated that technical features of the generative modeling component 102 are highly technical in nature and not abstract ideas. Processing threads of the generative modeling component 102 that process and/or analyze the imaging data 114 and/or the one or more latent random variables 116, etc. cannot be performed by a human (e.g., are greater than the capability of a single human mind). For example, the amount of the imaging data 114 processed, the speed of processing of the imaging data 114 and/or the data types of the imaging data 114 processed by the generative modeling component 102 over a certain period of time can be respectively greater, faster and different than the amount, speed and data type that can be processed by a single human mind over the same period of time. Furthermore, the imaging data 114 processed by the generative modeling component 102 can be one or more medical images generated by sensors of a medical imaging device. Moreover, the generative modeling component 102 can be fully operational towards performing one or more other functions (e.g., fully powered on, fully executed, etc.) while also processing the imaging data 114.

For example, the classification and/or the localization for the portion of the anatomical region can be presented as different visual characteristics (e.g., colors, sizes, hues or shades, etc.), based on a result of deep learning and/or the medical imaging diagnosis process 502. In another aspect, the medical imaging diagnosis process 502 can allow a user to zoom into or out with respect to the deep learning data associated with the multi-dimensional visualization. For example, the medical imaging diagnosis process 502 can allow a user to zoom into or out with respect to a classification and/or a location of one or more diseases identified in the anatomical region of the patient body. As such, a user can view, analyze and/or interact with the deep learning data associated with the multi-dimensional visualization for an input image (e.g., a medical image).

FIG. 9 illustrates a methodology and/or a flow diagram in accordance with the disclosed subject matter. For simplicity of explanation, the methodology is depicted and described as a series of acts. It is to be understood and appreciated that the subject innovation is not limited by the acts illustrated and/or by the order of acts, for example acts can occur in various orders and/or concurrently, and with other acts not presented and described herein. Furthermore, not all illustrated acts may be required to implement the methodology in accordance with the disclosed subject matter. In addition, those skilled in the art will understand and appreciate that the methodology could alternatively be represented as a series of interrelated states via a state diagram or events. Additionally, it should be further appreciated that methodologies disclosed hereinafter and throughout this specification are capable of being stored on an article of manufacture to facilitate transporting and transferring such methodologies to computers. The term article of manufacture, as used herein, is intended to encompass a computer program accessible from any computer-readable device or storage media.

Referring to FIG. 9, there is illustrated a non-limiting implementation of a methodology 900 for providing concurrent image and corresponding multi-channel auxiliary data generation for a generative model, according to an aspect of the subject innovation. At 902, synthetic multi-channel data associated with a synthetic version of imaging data is generated, by a system operatively coupled to a processor (e.g., by multi-channel generator component 104). The synthetic multi-channel data can be a multi-channel data sample. In an aspect, the synthetic multi-channel data can include a synthetic version of imaging data. Additionally, the synthetic multi-channel data can include one or more segmentations of the synthetic version of the imaging data. The synthetic version of the imaging data and the one or more segmentations can be associated with unique data channels. For example, in an embodiment, the synthetic multi-channel can include a first data channel associated with a synthetic image, a second data channel associated with first segmentation data indicative of a segmentation for the synthetic image, and a third data channel associated with second segmentation data indicative of a remaining segmentation for the synthetic image. In another embodiment, the synthetic multi-channel can include a first data channel associated with a synthetic image, a second data channel associated with first segmentation data indicative of a first segmentation for the synthetic image, a third data channel associated with second segmentation data indicative of a remaining portion of the first segmentation for the synthetic image, a fourth data channel associated with third segmentation data indicative of a second segmentation for the synthetic image, and a fifth data channel associated with fourth segmentation data indicative of a remaining portion of the second segmentation for the synthetic image.

At 904, multi-channel imaging data and/or the synthetic multi-channel data are predicted, by the system (e.g., by discriminator component 106), with a first predicted class set or a second predicted class set. In an embodiment, a class set can include a multi-channel image (e.g., channel level labels), an image label (e.g., image level labels) and/or clinical labels. The first predicted class set can be associated with a first classification (e.g., a first classification label) and the second predicted class set can be associated with a second classification (e.g., a second classification label). For example, an image level label can correspond to a “real” label for an image (e.g., a “real” classification label) or a “fake” label for an image (e.g., a “fake” classification label). In another example, a channel level label can correspond to a “real” label for a multi-channel image (e.g., a “real” classification label) or a “fake” label for a multi-channel image (e.g., a “fake” classification label). The multi-channel imaging data can be a multi-channel data sample. In an aspect, the multi-channel imaging data can include a real version of imaging data. Additionally, the multi-channel imaging data can include one or more segmentations of the real version of the imaging data. The real version of the imaging data and the one or more segmentations can be associated with unique data channels. For example, in an embodiment, the multi-channel imaging data can include a first data channel associated with a real image, a second data channel associated with first segmentation data indicative of a segmentation for the real image, and a third data channel associated with second segmentation data indicative of a remaining segmentation for the real image. In another embodiment, the multi-channel imaging data can include a first data channel associated with a real image, a second data channel associated with first segmentation data indicative of a first segmentation for the real image, a third data channel associated with second segmentation data indicative of a remaining portion of the first segmentation for the real image, a fourth data channel associated with third segmentation data indicative of a second segmentation for the real image, and a fifth data channel associated with fourth segmentation data indicative of a remaining portion of the second segmentation for the real image. The real image can be a two-dimensional image or a three-dimensional image generated by one or more medical imaging devices. For instance, the real image can be electromagnetic radiation imagery captured via a set of sensors (e.g., a set of sensors associated with a medical imaging device). The real image can be received directly from one or more medical imaging devices. Alternatively, the real image can be stored in one or more databases that receives and/or stores the real image associated with the one or more medical imaging devices. A medical imaging device can be, for example, an x-ray device, a CT device, another type of medical imaging device, etc.

At 906, a generative adversarial network model is trained, by the system (e.g., by training component 108), based on the first predicted class set or the second predicted class set for the multi-channel imaging data and/or the synthetic multi-channel data. The generative adversarial network model can be, for example, a generative network. The generative adversarial network model can be employed to generate images and/or corresponding annotations for the images. For example, the generative adversarial network model can be employed to generate medical images and/or corresponding annotations for the medical images. In an embodiment, a loss function can be generated based on the first predicted label or the second predicted label for the for the multi-channel imaging data and/or the synthetic multi-channel data. The loss function can be employed to tune the generative artificial intelligence model. For example, a multi-channel generator or a discriminator of the generative artificial intelligence model can be tuned based on the first predicted label or the second predicted label for the for the multi-channel imaging data and/or the synthetic multi-channel data. The loss function can be, for example, a cross-entropy error function. Furthermore, the loss function can be employed to improve classification output from the generative adversarial network model. In an embodiment, the loss function can be a loss function associated with loss between first data channel, the second data channel and/or the third data channel. In an embodiment, the loss function can be a loss function associated with loss between first data channel, the second data channel, the third data channel, the fourth data channel and/or the fifth data channel.

At 908, it is determined whether the generative adversarial network model satisfies a defined criterion. For example, it can be determined whether a multi-channel generator and/or a discriminator for the generative adversarial network model is adequately tuned. If no, the methodology 900 can return to 902. If yes, the methodology 900 can end. In certain embodiments, the methodology 900 can additionally or alternatively include generating first mask data indicative of a first ground truth mask for the first segmentation data. Furthermore, the methodology 900 can additionally or alternatively include generating second mask data indicative of a second ground truth mask for the second segmentation data.

The computer 1012 includes a processing unit 1014, a system memory 1016, and a system bus 1018. The system bus 1018 couples system components including, but not limited to, the system memory 1016 to the processing unit 1014. The processing unit 1014 can be any of various available processors. Dual microprocessors and other multiprocessor architectures also can be employed as the processing unit 1014.

The system bus 1018 can be any of several types of bus structure(s) including the memory bus or memory controller, a peripheral bus or external bus, and/or a local bus using any variety of available bus architectures including, but not limited to, Industrial Standard Architecture (ISA), Micro-Channel Architecture (MSA), Extended ISA (EISA), Intelligent Drive Electronics (IDE), VESA Local Bus (VLB), Peripheral Component Interconnect (PCI), Card Bus, Universal Serial Bus (USB), Advanced Graphics Port (AGP), Personal Computer Memory Card International Association bus (PCMCIA), Firewire (IEEE 1394), and Small Computer Systems Interface (SCSI).

The system memory 1016 includes volatile memory 1020 and nonvolatile memory 1022. The basic input/output system (BIOS), containing the basic routines to transfer information between elements within the computer 1012, such as during start-up, is stored in nonvolatile memory 1022. By way of illustration, and not limitation, nonvolatile memory 1022 can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), flash memory, or nonvolatile random access memory (RAM) (e.g., ferroelectric RAM (FeRAM).

By way of illustration and not limitation, RAM is available in many forms such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), direct Rambus RAM (DRRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM.

Computer 1012 also includes removable/non-removable, volatile/non-volatile computer storage media. FIG. 10 illustrates, for example, a disk storage 1024. Disk storage 1024 includes, but is not limited to, devices like a magnetic disk drive, floppy disk drive, tape drive, Jaz drive, Zip drive, LS-100 drive, flash memory card, or memory stick. The disk storage 1024 also can include storage media separately or in combination with other storage media including, but not limited to, an optical disk drive such as a compact disk ROM device (CD-ROM), CD recordable drive (CD-R Drive), CD rewritable drive (CD-RW Drive) or a digital versatile disk ROM drive (DVD-ROM). To facilitate connection of the disk storage devices 1024 to the system bus 1018, a removable or non-removable interface is typically used, such as interface 1026.

FIG. 10 also depicts software that acts as an intermediary between users and the basic computer resources described in the suitable operating environment 1000. Such software includes, for example, an operating system 1028. Operating system 1028, which can be stored on disk storage 1024, acts to control and allocate resources of the computer system 1012. System applications 1030 take advantage of the management of resources by operating system 1028 through program modules 1032 and program data 1034, e.g., stored either in system memory 1016 or on disk storage 1024. It is to be appreciated that this disclosure can be implemented with various operating systems or combinations of operating systems.

A user enters commands or information into the computer 1012 through input device(s) 1036. Input devices 1036 include, but are not limited to, a pointing device such as a mouse, trackball, stylus, touch pad, keyboard, microphone, joystick, game pad, satellite dish, scanner, TV tuner card, digital camera, digital video camera, web camera, and the like.

Interface port(s) 1038 include, for example, a serial port, a parallel port, a game port, and a universal serial bus (USB). Output device(s) 1040 use some of the same type of ports as input device(s) 1036. Thus, for example, a USB port may be used to provide input to computer 1012, and to output information from computer 1012 to an output device 1040. Output adapter 1042 is provided to illustrate that there are some output devices 1040 like monitors, speakers, and printers, among other output devices 1040, which require special adapters.
